Android device speed

Thank you, Jacqueline,


It sounds like I need to find a way to detect the processing speed of the device.

If it is below a certain level, it could adjust the div viewport for the map proportionally to the processing power.

It could reduce the size of the div, then reexpand it, using a 2d transform. By cutting the size of the div in half, vertically and horizontally, it would have a quarter of the number of pixels to process in 3D. Reexpanding would return it to the original number of pixels, but that is a 2d transform and would be much less of a burden on the processor.

The effect would be lower resolution and zoomed in, but that might be better than painfully slow map movements.

Do you have any suggestions on how to detect the device's graphics processing power?

Depending on manufacturer and model, the graphics card will vary in capability and available RAM. Screen resolution also makes a difference. I'm using older test devices because I figure if it works there it will work on most others. But my Samsung S4 runs more slowly than my S5 and they were released only a year apart. And my Nexus tablet, which is older than both Samsung phones, runs as well or better than either of those, probably because it has a lower screen resolution. I'm not sure there's a standard you can rely on.

When you get into the higher range phones they can be quite acceptable. The same app that lagged on my Samsung ran fine on someone else's Pixel.
